I kinda had the same problem with some pedals I made. I bought like 100 super bright LEDs for ones I was making thinking they'd look really cool. When I look at the pedals to fiddle with the knobs I about go blind. I just gave in to their power. Too lazy to switch them out. I guess if you're going to switch yours out be carefull not to fry yourself. Tube amps are dangerous bizness.
